I am using elasticsearch and have outgrown one server.
Therefore, I would like to create a cluster configuration of two elasticsearch servers with the following manual.
I have deployed elasticsearch on two servers, but I get connection refused.
I do not know the cause of this problem. Please give me some advice.
